Sažetak
Heterocyclic molecular systems with pronounced and diverse spectral responses are among the most extensively studied classes of organic compounds. Design and development of small molecules for (chemo)sensing and optoelectronic applications is of great interest in organic chemistry and sensing technology [1]. Structural similarity of benzimidazole (BI) nuclei with naturally occurring purines enabled the applications of such molecules in molecular biology or medicinal chemistry. The BI moiety can serve as a multifunctional unit in molecular systems and an especially attractive building block in D-π-A systems for different applications in optoelectronics and as pH sensors [2]. The photophysical and chemical properties of push-pull systems are defined by the position, number and electron donating and accepting strengths of donor and acceptor groups and their chemical nature [1]. Herein we present multifunctional D-π-A molecular systems containing an N, N-diethylamino group as a pH sensitive donor group connected to the electron accepting substituents like cyano group and the pH sensitive benzimidazole moiety. We have prepared acrylonitrile, Schiff base and iminocoumarin derived benzimidazoles (Figure 1). The photophysical characterisation and computationally supported determination of species involved in prototrophic equilibria, including their respective pKa values, have been performed in order to better understand the effects of the D-π- A molecular structure on the UV–Vis spectral properties and pH sensing potential of these chromophores.
